The SQ-MELF package (D-5C supplier device code) is a surface-mount ceramic barrel — the same footprint as a standard MELF but with a square body for better solder-joint inspection and automated handling. The -55°C to 175°C operating range means this part can sit on a hot backplane or near an engine bay without derating concerns. ## Clamping voltage and pulse current — sizing the protection margin With a 24V reverse standoff and 41.4V max clamping, the 1N6473US/TR protects 24V DC buses — industrial control supplies, automotive power distribution, or telecom line cards — where the transient energy stays under 1500W. The 36.5A peak pulse current rating gives the designer room to calculate the actual clamping voltage at the expected surge level; the 41.4V is the ceiling at full rated current. The device is not intended for power-line protection (no power-line protection flag), so keep it on the secondary side — after the bridge rectifier or DC-DC converter output. ## Active production — sourcing posture Microchip lists the 1N6473US/TR as Active. We source this part against an RFQ — confirm your annual volume and target price, and we will quote firm. No stock-holding claim; each order is sourced from Microchip authorized channels or vetted open-market inventory.","metaTitle":"1N6473US/TR TVS Diode – 1500W, 24V Standoff, SQ-MELF","metaDescription":"1N6473US/TR from Microchip Technology: 1500W peak pulse power, 24V reverse standoff, 27V breakdown, 41.4V clamping.
